Abstract: The present invention relates to a context-based QA generation architecture, and an object of the present invention is to generate diverse QA pairs from a single context. To achieve the object, the present invention includes a latent variable generating network including at least one encoder and an artificial neural network (Multi-Layer Perceptron: MLP) and configured to train the artificial neural network using a first context, a first question, and a first answer, and generate a second question latent variable and a second answer latent variable by applying the trained artificial neural network to a second context, an answer generating network configured to generate a second answer by decoding the second answer latent variable, and a question generating network configured to generate a second question based on a second context and the second answer.

Abstract: A light detection and ranging (lidar) device includes: a lower base; an upper base; a laser emitting unit for emitting a laser in a form of a point light source; a nodding mirror for transforming the laser in the form of the point light source to a line beam pattern which is perpendicular to the lower base, wherein the nodding mirror reflects the laser emitted from the laser emitting unit; a polygonal mirror for transforming the line beam pattern to a plane beam pattern and receiving a laser reflected from an object; and a sensor unit for receiving the laser reflected from the object via the polygonal mirror.

Abstract: The present invention relates to a light detecting and ranging (LiDAR) device for obtaining information on a distance from an object using laser light.

Abstract: The present disclosure relates to a portable printer including a main body in a portable form which is capable of accommodating a cartridge having a nozzle for delivering a printing material to a target having a soft or hard surface, a seating part which is provided to be exposed to an outside from a lower portion of the main body to face the surface of the target and at least partially surrounds the nozzle, a roller provided respectively at the front and rear of the nozzle at the lower portion of the main body with respect to a direction in which the main body moves along the surface of the target to deliver the printing material to the target, and a printing adjustment unit configured to adjust a height difference between the nozzle and the roller to adjust a height difference between the nozzle and the surface of the target.

Abstract: A video masking processing method and a video masking processing apparatus using the same are provided. The video masking processing method photographs frames constituting a video, detects at least one masking area to be masked in the photographed frames, masks an image in the detected at least one masking area, inserts masking information including information on the masking into the photographed frame, and stores the frame which has undergone the masking and has the masking information inserted thereinto. Therefore, since images related to personal information in a photographed video are masked, a user does not infringe others' privacy in a video normally photographed by a CCTV or a dashboard camera.

Abstract: The present invention relates to a pharmaceutical composition for preventing or treating pulmonary fibrosis comprising an isothiocyanate-based compound and a biguanide agent as active ingredients, a method for preventing or treating pulmonary fibrosis using the composition, and use of the isothiocyanate-based compound and the biguanide agent for the preparation of the prophylactic or therapeutic agent for preventing or treating pulmonary fibrosis. The pharmaceutical composition comprising the isothiocyanate-based compound and the biguanide agent as active ingredients of the present invention can be used to stably prevent or treat pulmonary fibrosis for which specific therapeutic agents have not yet been known, and thus it can be widely used for health and welfare improvement through treatment of pulmonary fibrosis.
